Guild Wars 2

Dungeons:
I think that you should make more tactical combat fight. . Atm my experience so far at most of the fights is " Equip utility skills that are usefull for this fight, use them on cd or spread them on the floor and some mob will trigger them".
So you might have to add “Warnings” for boss abilities that 1-shot u. Ofc to do that you have to add abilities that one shot you and you can avoid by hidding behind something or my using an ability at the right time. The point behind this is that players has to use their abilities correct and protect their grp.
Also to work you need bigger boss rooms inside instances. Anyways i need more tactics not a random thing.

Party: I think that currently if 1 person accept to kick someone or 1 person accept someone in the party then he enters, but this is the minority. Dont we need a vote that pass with 3 ppl from 5 and not for 1?(or maybe a leader?).
Also make more visible the offline/online indication.

Vendors: Many vendors selling things with currency that we dont recognize(like the vendors that you get dungeon armor). So i am opening my bag and my vendor and trying to figure out which emblem is for each vendor. When you mouseover the currency you should get the name of the currency.

WvWvW: Use an afk timer that kicks ppl when are afk for 15 min (you could increase the time limit later when the population drops). Also loot is an issue, you should add loot automatically at WvW.

Trading Post: Add an option on advance search that shows you only what you can wear or use (example: leather)
